The most legendary road trip in Chilean Patagonia
The Carretera Austral, officially Route 7, stretches roughly 1,240 km (770 miles) from Puerto Montt to Villa O'Higgins, cutting through fjords, glaciers, temperate rainforest and volcanoes. Large sections south of Coyhaique are still gravel, so realistic average speeds sit around 50-60 km/h (30-37 mph). This is not a highway trip; it's a slow journey through villages of fewer than 2,000 people and landscapes that feel genuinely empty.
What makes it unique
Unlike other Pan-American routes, the Carretera Austral was only built between 1976 and 1996, and several stretches still rely on ferries because the fjord-and-channel geography makes a continuous land route impossible.
First leg: Puerto Montt, Hornopiren and Pumalin Park
From Puerto Montt, drive to Caleta La Arena for a 30-minute ferry crossing (about CLP 10,000 per car), then continue to Hornopiren, where a second ferry (Hornopiren-Leptepu, 4-5 hours through the Comau fjord) is needed to keep heading south. Book this crossing weeks in advance during January-February.
Pumalin Park, created by Douglas Tompkins and later donated to the Chilean state, protects ancient alerce forests and Chaiten Volcano, which erupted in 2008 and buried part of the nearby town. Entry is free, and short trails like Sendero Cascadas (45 minutes) are perfect for stretching your legs.
Futaleufu: world-class whitewater rafting
The turquoise, glacier-fed Futaleufu River is considered one of the best rafting rivers on Earth, with rapids ranging from class III to class V. Outfitters such as Bio Bio Expeditions or Futaleufu Explore run half-day trips from about USD 60-90 and full-day trips from USD 110-140, gear and lunch included. Kayaking, fly fishing and floating calmer sections are also popular options.
Puyuhuapi and the Hanging Glacier
Puyuhuapi, founded by German settlers in the 1930s, is the gateway to Queulat National Park, where the Ventisquero Colgante (Hanging Glacier) sends waterfalls tumbling straight off the ice. Entrance costs around CLP 6,000-8,000, and visitors can choose the roughly 3-hour round-trip hike or take a boat closer to the glacier's base. Nearby, the Puyuhuapi hot springs offer thermal pools facing the sea, reachable only by boat.
Coyhaique, Cerro Castillo and the Marble Caves
Coyhaique is the regional capital and the best place to top up on fuel, cash and supplies before continuing south. Cerro Castillo National Reserve, named after its dramatic rock spire, offers a 3-4 day trek often compared to Torres del Paine's W circuit, but with a fraction of the crowds.
Further south, boat tours to the Marble Caves (Capillas de Marmol) depart from Puerto Rio Tranquilo. These limestone formations were carved by Lago General Carrera's waves over thousands of years. A one-hour tour costs between CLP 20,000 and 30,000 per person; go early morning, when the lake is calmest and the light brings out the turquoise tones in the rock.
Practical tips: car, buses, ferries and fuel
- 4x4 rental vs bus: a rental car or pickup gives full freedom but costs CLP 45,000-70,000 per day; companies like Buses Becker or Queilen Bus cover the main stretches more cheaply but on limited schedules.
- Hitchhiking: common and relatively safe in this region, though traffic is sparse outside peak season.
- Ferries: book key crossings (Hornopiren-Leptepu, Puerto Yungay-Rio Bravo toward Villa O'Higgins) with Naviera Somarco at least 4-6 weeks ahead in summer.
- Fuel: gas stations are scarce and sometimes close early; always carry a spare fuel can, especially between Coyhaique and Villa O'Higgins.
- Recommended time: 2 to 3 weeks to travel it without rushing between stops.
- Best season: November to March, with December-February as peak season (more services, but also more crowds and higher prices).
